A thermally adaptive wall covering is operable to cover at least part of a wall and to move in response to a change in covering temperature. The wall covering includes a laminated composite panel with first and second panel layers and an intermediate connecting structure that connects the panel layers relative to one another along an interface defined between the panel layers. The first and second panel layers have, respectively, first and second coefficients of thermal expansion that are different from each other and cause expansion and contraction of the corresponding panel layers along an interface therebetween. The connecting structure permits expansion and/or contraction of each panel layer relative to the other panel layer in response to the covering temperature change so that the panel flexes.

A fastener configured to catch the edges of a plurality of wallboards with the use of one anchoring element is disclosed. The fastener comprises a convex plate of circular shape having an anchoring hole, which is configured to allow the insertion of an anchoring element, located at the center of the convex plate. The method for using such a fastener comprises placing the fastener at a location where the surface of the convex plate covers a plurality of edges of a plurality of wallboards; inserting an anchoring element (e.g., a screw or nail) through the anchoring hole so that the anchoring element anchors onto a support element; upon completion of the insertion of an anchoring element, the surface of the convex plate will be essentially flat and flush with the surface of the plurality of boards.

A panel fastener and panel fastening system are provided. The panel fastener includes a body having a collar and an elongated shank extending from the collar. The elongated shank defines an interior space and having a penetrating tip disposed at an end opposite of the collar. The panel fastener also includes a substrate fastening portion configured to be driven into a substrate and a holding mechanism connected to the substrate fastening portion and configured to engage the substrate.

The invention relates to a screw, comprising a drive, a drilling tip for producing a bore, said bore having a bore axis and a bore diameter, which drilling tip is spaced apart from the drive in a drive-in direction, and a shaft, which extends from the drive to the drilling tip, wherein the shaft has a stop section, which can be fed through the bore when the drive-in direction of the screw is tilted in relation to the bore axis and which has a stop surface for blocking the feeding of the stop section through the bore when the drive-in direction of the screw is oriented parallel to the bore axis.

The invention relates to building materials, in particular to attachment of siding boards, such as composite boards, or fiber cement boards on building siding. A clip to securely attach the boards is disclosed. The clip may be used with our without a shaped foam insulation board. A method to use the clip is also disclosed. Various embodiments of the clip are provided.

A facade module for separating an interior from an exterior of a building volume includes: a partition plate, including an inner face and an outer face, the partition plate including an inner glazed layer forming the inner face; and a fastening element of the partition plate suitable for fastening the partition plate to a building structure. The partition plate includes at least one stone layer forming the outer face of the partition plate and/or extending over the inner glazed layer.

The object of the invention is a unit fixing insulation to the wall intended both for styrofoam insulation as well as for mineral wool insulation. A unit fixing insulation to a wall, according to the invention, is formed with the locating sleeve on which a pressing sleeve is slidably mounted, constituting an integral unit with a circular pressing plate provided with slitting teeth arranged along the circumference of a circular plate and the locating sleeve is ended at one end with an expansion zone and at the other end with a circular plate, whereas the locating sleeve houses an expansion element, preferably in the form of a screw. A unit characterised in that the expansion element has a head embedded permanently in the sleeve with an outer thread and a polygonal hole is provided within the sleeve, whereas a pressing plate is ended with a circular flange which houses the insulating cap, while the teeth of the pressing plate have side and front sharp edges.

A system and method for securing a panel to a wall. The panel mount system includes a backing strip comprising a mounting plate with a front face for contact with the panel, an opposed rear face, and a plate opening extending therebetween. The mounting plate includes a rim extension extending from the front face around the plate opening for extension through the panel. The rim extension has an internal coupling component, and is further dimensioned to receive a body of a screw therethrough. The screw comprises a head, and the body extends from the head for securement to the wall. The body has an external coupling component configured to releasably couple with the internal coupling component of the rim extension when the body of the screw extends through the rim extension.
